A study of consumer smoking habits includes 193 people in the 18-22 age bracket (60 of whom smoke), 127 people in the 23-30 age

Thepotemich [5.8K]

Total number of people in the sample = 193 + 127 + 96 = 416

Probability of picking 23-30 year old = 92 /416 = 0.2212 ( not including the people who smoke)

Number of people who smoke = 60+35+23 = 118 people

Prob(someone who smokes) = 118/416 = 0.2837

So required probability = 0.2837 + 0.2212 = 0.505 (answer)

Use linear regression to find the equation for the linear function that best fits this data. Round both numbers to two decimal p

natta225 [31]

Answer:

The equation of the linear function that best fits the data is,

y = 18.66x + 66.87.

Step-by-step explanation:

The line of best is of the form: y = mx + b.

Here, m = slope of the line and b = intercept.

The formula to compute the intercept and slope are:

$b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}$

$m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}$

Consider the table below for the values of ∑ X, ∑ Y, ∑ X² and ∑ XY.

Compute the value of intercept and slope as follows:

$b=\frac{\sum Y.\sum X^{2}-\sum X.\sum XY}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(793\times91)-(21\times3102)}{(6\times91)-(21)^{2}} =66.867$

$m=\frac{n.\sum XY-\sum X.\sum Y}{n.\sum X^{2}-(\sum X)^{2}}=\frac{(6\times3102)-(21\times793)}{(6\times91)- (21)^{2}} =18.657$

The line of best fit is:

$y=mx+b\\y=18.657x+66.867\\y=18.66x+66.87$

Thus, the equation of the linear function that best fits the data is y = 18.66x + 66.87.

Bunny Hill Ski Resort charges $35 for ski rental and $10 an hour to ski. Black Diamond Ski Resort charges $40 for ski rental and

Aleonysh [2.5K]

Bunny Hill Ski
10x+35

Diamond Ski
5x+40

To find when both resorts cost the same prices set them equal to each other

10x+35= 5x+40
Minus 35 over
10x = 5x +5
Minus 5x over
5x = 5
X= 1

When x= 1 both of the resorts will cost the same price. You can check by substitute x with 1. Hope this helps!
